The Siemens HLD63B500 is a 500-amp, 3-pole, 600V high-AIC L-Frame molded case circuit breaker from the Sentron Series HLD line. It delivers a 65kAIC interrupting rating at 480V and 100kAIC at 240V, making it ideal for high-fault-current industrial main distribution applications. The HLD frame covers 400 to 600 amps with an interchangeable trip unit and ships assembled with aluminum/copper lugs. The HLD63B500 is compatible with Siemens NEMA-type switchboards and is a direct replacement for legacy ITE HLD units.
